Question

An online poll conducted by Ipsos Reid on behalf of Rogers Wireless in May 2009 concluded that "two in ten (17%) of cellphone and smartphone users typically access the Internet on a daily basis from their phone."3 Although this online poll was not a probability sample, assume that it was. 1,403 Canadians were surveyed. Is there enough evidence, at the 4% level of significance, to conclude that more than 15% of all Canadian cell phone and smartphone users typically access the internet on a daily basis from their phone?
